Product Description


The M18™ REDLITHIUM™ HIGH DEMAND™ 9.0Ah Battery Pack delivers up to 5X more run-time, 35% more power, and runs 60% cooler*. The battery is best optimised for high draw products and sustained run-time applications, and it provides the next, large step towards full corded replacement when paired with the M18 system of solutions. It maintains full power and runs substantially cooler through heavy applications, allowing users to push their cordless tools harder and longer than ever before.
